Tweco 1160-1430 Mig Contact Tip 0.078 in Wire 1.5 in

Product Description

The TWECO 1160-1430 is a threaded MIG welding contact tip designed for 3/32-inch (0.078 inch) wire and rated for heavy-duty welding applications up to 600 amps. Machined from 122 DHP copper alloy tubing, the tip delivers consistent electrical conductivity and a smooth inside diameter surface held to a tolerance of plus or minus 0.003 inches. The nominal inside diameter is 0.09 inches with an outside diameter of 0.375 inches and an overall length of 1.5 inches. Licensed welding technicians and MIG welders working in fabrication, manufacturing, and structural applications install this tip as a standard consumable replacement on MIG welding guns.

This contact tip is suited for heavy-duty MIG welding environments where consistent wire feed and reliable electrical contact are critical. The M8 x 1.25-6g thread size provides a secure, proper-contact fit with a standard gas diffuser when threaded into a compatible MIG gun assembly. It is intended for continuous or high-cycle production welding applications where amp loads approach 600 A. Each tip is marked with the part number and wire diameter to simplify inventory management and quick identification during gun changeovers on the shop floor or in the field.

Installation Notes

Contact tips are installed and replaced by qualified welding technicians or MIG welders during routine gun maintenance. Always power down the welding machine and allow the gun to cool before removing or installing a contact tip. Use appropriate tip removal tools to avoid damaging the gas diffuser threads. Inspect the gas diffuser for thread wear or spatter buildup before threading in the replacement tip.
